HEAT-REFLECTOR FOR STOVESL SPECIFICATION forming part Of Letters Patent N0. 706,996, dated August 12, 1902.

T0 aZZ whom it may concern.-

Be it known that we, BARRETT C. OBLINGER and ALBERT H. OJBE'ATTY, citizens of the United States, residing at Independence, in

the county of Jackson and. State of Missouri, have invented new and useful Improvements in Heat-Reflectors for Stoves, of which the following is a specification.

Our invention relates to heat-reflectors for stoves; and the objects of our invention are, first, to cause the gases rising from the fire to be consumed within the stove instead of passing up the chimney, and,'second, to reflect drawn up into contact with the lower edge ofsaid reflector the interior of the stove is thereby cut off from the stovepipe, and the amount of draft through the stovepipe may be regulated by adjusting the bell from or toward the reflector.

Our invention will now be fully described with reference to the accompanying drawings, in whichl Figurel is a vertical sectionalviewof our invention applied to a stove; the 'stovebeing broken away to expose the same. Fig. 2 shows a modified means for adjusting the bell.

1 designates the wall of a stove of the kind which is fed with fuel from a door inthe side- 2 designates the top plate, to which the Stovepipe-3 is connected. Beneath the plate 2 is an annular casting 6, referred to hereinafter as a reflector. This reflector is supported by logs or brackets 4, which are riveted to the stove-wall 1. The walls of said reflector incline downwardly and inwardly and are curved, as shown in Fig. 1. "The diameter of the lower edge thereof should be about twothirds of the inside diameter of thestove. The upper edge of ;therefle ctor fits the'wall' of the stove.

Within the circular opening in the bottom of the reflector 6 is hung a cast-iron bell 7,

which serves the double purpose of a cut-off or'damper and a reflector for reflecting; some of the heat of the fire downwardly. The bell is supported by a screw threaded stem 8, which extends through'a threaded hole in the top plate 2. I WVe prefer to secure the stem 8 rigidly and tightly to the top of the bell 7, and one means fordoing sois by a not 9, as shown. A crank 10 is rigidly secured to the upper end of the stem 8 for turning the same, and there-- by changing the height of the bell 7.

A modified devicefor moving the bell 7 up and down is shown in Fig. 2, in which 12 designates the bell, supported by a screw-threaded stem 13, passing through a threaded hole in its top. The stem 13 passes through a hole in the stove-lid 14 and is connected to a crosspin 15, secured eccentrically in a verticallyslotted cam 16, on which is a handle 17, by which the cam 16 may be turned halfway around, bringing the handle to the position shown in dotted lines. This movement lowers the pin15, stem 13, and bell 12 to the position shown in dotted lines. The finer adj ustment of the bell 12 is effected by turning the handle 17 horizontally, thereby rotating the stem 13 and raising or lowering the bell, the latter being held against rotation. h The operation of the entire device is as follows: In ordinary stoves the draft carries up the gases of combustion before they are burnedor consumed. In this device the bell 7 and the side reflector 6 become highly heated, and the rising gas is partly confined in the annular space below the side reflector, in which the gas will have a circular movement. The heat of the bell and the reflector ignites the gas, which then burns continuously and raises the temperature of said parts still higher. When the fire is started in the stove, the bell 7 is lowered to give the fire a full draft. As the fire gains headway the bell may be raised to give anydesired draft, as the products of combustion must pass between the bell and the side reflector to reach the chimney. I

Having now fully described our invention, what we claim as new, and desire to secure by Letters Patent of,the UnitedStates, is

1. A stove having'a smoke escape-opening in the top of its combustion-chamber, a re flector depending from its top and extending around its sides, said reflector being at its upper edge tightly joined to the top of the stove, having downwardly-converging sides and being open on its lower side, the smoke escape-opening being within the radius of the reflector and at one side thereof, and a bell of approximately the same diameter as the mouth of the reflector and disposed mouth downward below the reflector, whereby the bell and reflector become highly heated, retard the escape of unconsumed combustible gases and ignite the same, substantially as described.

2. A stove having a smoke escape-opening in the top of its combustion-chamber, a reflector depending from its top and extending around its sides, said reflector being'at its upper edge tightly joined to the top of the stove, having downwardly-converging sides and being open on its lower side, the smoke escape-opening being Within the radius of the reflector and at one side thereof, a bell of approximately the same diameter as the mouth of the reflector and disposed mouth downward below the reflector, whereby the bell and reflector become highly heated, retard the escape of unconsumed combustible gases and ignite the same, and means to adjust the bell vertically to vary the width of the space between the same and the reflector, and thereby regulate the draft, substantially as described.

, 3. In combination with a stove, an annular heat-reflector supported therein, its periphery fitting within the stove-wall, the top plate of the stove having a screw-threaded hole therein, a vertical screw-threaded stem passing through said hole and extending through the top of the stove, means for rotating said stem, and a bell supported by said stem, within and below the lower edge of saidannular reflector; substantially as described.

In testimony whereof we aflix our signatures in the presence of two witnesses.
